1 l This invention relates to dust bins or dust receptacles, and tocontainers in which mops may be shaken to remove the dust from the mopand more particularly to dust bins for shaking'dust from mops to avoidshaking the mop out of the window or elsewhere where the dust would beobjectionable, though it is noted that in some of the claims'theinvention is not limited to dust bins.

Objects of the invention are to provide an improved closure means forthe dust bin and to provide automatic means for closing and open ing theclosure means. I

Other objects of the invention are to provide improved bafiles withinthe bin, and improved means for removing the dust from the-bin.Additional objects of the invention are to effect simplicity andefiiciency in such dustbins and to provide'an extremely simple dust binof this kind which is convenient, durable, clean and reliable inoperation, and easy to operate'and economical to manufacture. I H aStill other objects of the invention will appear as the descriptionproceeds; and while herein details of theinvention are described in thespecification andsome of the claims, thegin'vention as described in thebroader claims is not limited tothese and many and variouschanges mayfbemade without departing from the scope of the invention as claimed in thebroader claims. N

The inventive features for the accomplishment of these and other objectsare shown herein in connection with a dust bin which briefly stated,includes a container havingfa top wall and a curved sidewall, said topwall having a stationary slot extending inwardly from-theperiphery, saidside wall having below said slot a large. opening communicating withsaid slot.- A rotary plate or disk 'rotatably mounted on the top wallcarries anapron engaging'said curved wall and adapted op'ening and theslots-respectively,whereupon-the slot 6 Claims. (01. 15-104) to close orclear said opening'wh'enthe-plate is dle on the edge of the curved slotand the closing of the apron over said opening, whereupon the handle maybe shaken to agitate the mop in the barrel to remove dust therefrom.Outward lateral'movement of the mop automatically opening the apron forthe removal of the mop.

Gratings and bafiies within the container against which the mop may beused, assist in removing dustand dirt from the mop to be removed fromthe container as explained hereinafter.

In the accompanying drawing showing, by way of example, one of manypossible embodiments of the invention:

Figs. 1 and 2 are respectively front elevation and plan'showing the dustbin in closed posi- Figs-3 and lare respectively front elevation andplan showing the dust bin in open position;

Fig. 5 is a horizontal sectional view, partly in elevation and drawn toa larger scale, showing the dust bin in open position, the section beingtaken substantially on the line 55 of Fig. ;6, looking in the directionof the arrows of said line; and

Fig. 6 is a vertical sectional view, partly in elevation showing therear part of the interior of the dust bin, the section being takensubstantially on the line 66 of Fig. 5, looking in the direction of thearrows of said line. I

This invention is shown embodied inan automatically closing dust bin formops, said dust bin comprising a cylindrical bin or barrel l0 having acircular top wall ll (Fig. 6) a cylindrical side wall l2, upper andlower gratings l3, l4 and uncrossed parallel bars I5, Iii-spacedfrom-the top wall and the bottom plane of -the-barrel re-- -2 I in whichthe lower part'of the barrel removably rests. A radial outlet nozzle 22mounted on and projecting from the side wall l2 communicates with thebarrel below the lower grating,the wall 2! of the tray havinga cut-awaynotch 23-receivhandle maybe pushed to the inner end 'of th'e Tstationary slot causing the camming of the han-v ing the nozzle. ,The'nozzle is adapted'to receive a a hose 22a establishing communicationbetween .the iriterior of the barrel below the lower grat' ing and thesuction of a vacuum cleaner or other. source of. suction for removingthedust from the barrel. Obviously this nozzle may be omitted, and dustemptied by removing the barrel from the tray and emptying the dust fromthe tray. The tray bottom may be secured to the side wall [2 if desired,and the tray wall 2| omitted.

The circular top wall H is provided with a substantially radial slotwide enough to receive a mop handle 26a and extending through theperipheral edge of the top wall and extending near and offset from thecenter of the top wall. The side wall I2 of said barrel has below theouter end of the slot 25 a large opening 21 (Figs. 3 and 5) in the frontpart of the barrel, large enough to admit the mop 26 and extending tonear and below the top wall to provide an upper strengthening flange 28.joining the.

top wall and having an upper vertical slot extension 29 communicatingwithsaid slot 25iand large enough to admit the mop handle Ma-to.

said slot 25.

A pivot pin, eyelet or rivet 30', secured in the center of the top wallrotatably receives. a- 118-. ripherally projecting rotary disk 3| on thetop wall. and having-a central-opening rotary on said pin 30. The disk3-! maybe cut away at the chain line. 32, or otherwise designed, to savematerial.

Said disk 3| carries a closure apron secured on the'periphery of saiddisk and enga ing the side face of the barrel and adapted to completelyclose said large opening 2"I- when the disk and.. apron. are. in oneposition of rotation shown-in. Figs. 1, Zand. 5.and.to clear saidopening. which the disk] and apron are in-a second andopen position ofrotation asshown in Figs. 3 and 4. Said disk is provided with an atleast partially curved or spiral slot '36 wide enough to. receive the:mop handle; 26a and having its inner end registerable with the inner endof the slot 25. when the disk and apron are in closed position as inFi-g. 2 and having itsouterend registerabl e-with the outer end ofthexslot 25 when the apron and disk. are; said second. and open.position, asshownin Figs. 3 and 4, whereby said outer ends mayreceivethe mop handle 26a, whereupon the handle 2611. may be pushed to theiinner end of the slot 25 causing an edge of thecurved or. spiral slot36.- to cam o n the handle'until; the handle reaches the inner endoft-heslots, causing partial rotation of the disk and registration ofsaid inner ends and theclosing of the apron,35:- over said large opening21, whereupon thehandle 250, may be shaken to agitate the mop '26 in thebarrel to remove dust thereirom;while the dust isconfined in the barrelby the apron and disk, and isfree to drop through the gratingI-4---tothe lower part of the barrel-to be drawn through the nozzleinto. the hose Zimconnected to; the suction of a vacuum cleaner or, to-be emptied by removal of the. tray 20,; .or otherwiseremoveda Vniterthe dust has been removed-from the: mop, outward movement oftheghandle 26a to. theperiphery of the top wall; ti againcauses'registration ofssaid-outenendsrofithe slots 25,. 36, thusopening-the front opening 27.- and allowing. removal of the mop.

A guide strip: 3:9 is secured around the side wall Just-below the largeopening andhaving its per. reinslightlv.out dly ofi-set to P videatrack-groove .49; lowenelige ofthe apron 3.5 slides' andis; guided;

(Fig; 5) in. which the anda-Estop. strip ,4 l' securedto. the.sidewallgnear .feetiongthe foot; restsfih.

its margin nearest the opening off-set from the side wall to provide akeeper groove 42 in which the adjacent edge of the apron is received andstopped when in closed position. Said strips 39, 4| serve to keep theapron securely closed when the mop is being agitated in the barrel. Astop bracket 43 is secured on the outer face of the barrel in positionto stop the apron in fully open position.

A half-sleeve M large enough to receive half of, and guide, the mophandle has a lower outturned flange 45=secured to thedisk around theinner end of the. spiral slot and :positioned to allow the sleeve to besubstantially coaxial with and to engage and guide the mop handle justout. of. contact with the inner end edges of the slots. Downwardlyprojecting horizontal spaced strengtheningbars 46' of angularcross-section are secured to said flange 28 and said top and .sidewalls, for strengthening the top wall.

' Inwardly projecting parallel spaced arcuate bafiles 46?:0f roundcross-section are mounted on brackets 41 secured to said side wall, thebaffles terminating at'said large openingZ'l. Saidbafiles 46.andgratings l3, l4 facilitate removalof dust from. the mop. when thelatter is beat and rubbed against the baffles and gratings. The uppergrating I3 serves, to protect thetop wall.

A pair. of, plate-like. foot rests 4.8 secured. to the. lower part ofthe tray and. projecting tollie flat on the. floor or other. supportsupporting the tray are adapted to be stepped on by the oper ator, forholding. the barrel while the mop is being manipulated or when thebarrel is removed fromthe tray; and handles 49v inv the side of. thebarrel facilitate handling the. dust. bin and re.- moving. the barrelfrom thegtray.

The various parts o-f the: dustbin maybe held together-by welding,soldering or in anysuitable known manneri I The operation of the dustbinwill be; easily understood from' the foregoing, and is. now only brieflysummarized as follows; 5 l,

With the bin. assembledin. o-pen,p,ositionifas in Fig. 2, the operatormerely places the mop to be. cleaned approximately .in the. position ofthe dottedlines of Fig. 6 withflan intermediate part of the handle intheeregistering outer. ends of the slots 25 and36 and the, space 50(Fig.5) between the, ends: of the interrupted ring. Then the. uprighthandle is forced inwardly to the innerendsof the slots '25, 3.B. .andbetween adjacent bars l5a. of: the upper-grating, thebars 1511beingparallel to; the slot 25, and connectedby a curved-cross bar 5!just.beyend-- the innerv end of the slot 25.; The stated. inwardmovement automatically: closes. the apron 35..
